摘要： The invention relates to an electro-optical cell (1) comprising a first (2) and a second (3) support member, an electro-optical medium (5) between the support members and an electrode arrangement (11, 12) on the support members such that an electric field can be applied, in the electro-optical medium, perpendicular to the support members, aligned with the support members or at an oblique angle (7) with respect to the support members. The electro-optical cell further comprises layers (14) of material with different dielectric constant between the support members in order to reduce the inhomogeneity of the electric field lines in the electro-optical medium. By having a layer of cholesteric liquid crystals between the support members, the electro-optical cell will function as a colour filter for varying applied fields. By introducing a particle suspension in a medium between the support members, an electro-optical cell is created that can be switched between a transmissive, reflective and partly deflective state.

摘要： A switchable transflector (1) comprises a suspended particle device (SPD). The transflector (1) may be switched into transmissive, reflective or intermediate states by applying one or more electric fields to a particle suspension (2). An enhanced reflectivity state may be achieved by applying two mutually orthogonal electric fields simultaneously. An intermediate state may be achieved by applying a non-saturating electric field or by applying two or more electric fields alternately according to a timing scheme. The transflector (1) may be maintained in a given state by applying voltage pulses at intervals less than a relaxation time associated with the SPD 1. The transmittance and reflectance properties of the transflector (1) may be tuned in accordance with the output of a light sensor (14). The transflector (1) may be incorporated in a transflective display (15)which comprises a display device, such as an LCD (16). In order to illuminate the LCD (16), the transflector (1) is arranged to transmit light (20) emitted by a light source (17) and/or reflect ambient light (21). The relative proportions of transmitted and reflected illumination may be determin by the output of the light sensor (14).
